Andres,

There are a good many "classical singers" who simply have a "beautiful" voice and a good ear(and often the looks to match)--and I have worked with a few of them, and saw many of them in music school--they are taught their parts, note-for-note with someone holding their hand, and lessons that are free because they have such great talent(much to the chagrin of some of the other singers, who have voices that are only "good" and must work to pay for lessons, often from a less prestigious teacher)--

Sooner or later, they always advance to a place where their talent is not so exceptional as it seemed to be in the local music society, the church or school choir, or the Young Peoples Musical Theatre Ensemble--anyway, you know they type--
